[IRCA] 1107 from Asia
Gary DeBock and I have both been watching this frequency lately, in
fact I've been watching it all season. Using my detailed spectrum
display on the 313e (4 kHz = about 4" in a oscilloscope-type display)
I can see that usually there is an on-frequency carrier there that is
ragged and muddy... and the graphic spike, clean, crisp and nearly
vertical with a good transmitter is all rough and it is more spread
out at the base than normal. There is usually at least one well-tuned
transmitter there, too. Often, that is HLAV from South Korea, but it
has been one of the two or three smaller JJ commercial stations, too.
Usually the two (or three?) signals combine to just produce garbage
audio. However sometimes, usually near band-fade, the nasty
transmitter will fade out first, or the clean signal will
dominate. This same situation was going on all last Fall season,
too. Does anyone have any idea who the nasty transmitter
is??? Surely not Urumqi???
